The interrupt registers accessed in ixgbevf are more similar to the igb style registers than they are to the ixgbe style registers. As such we would be better off setting up the code for the EICS, EIMS, EICS, EIAM, and EIAC like we do in igb instead of ixgbe. Signed-off-by:

Currently the VF driver is processing all of the transmits in interrupt context. This can be messy since the Rx is all handled in NAPI and this may result in interrupts being disabled. In order to resolve this move all of the Tx packet processing into NAPI and combine all of the interrupt and polling routines into just a pair of functions. Signed-off-by:

For most cases the ixgbevf driver will only ever contain a single Tx and single Rx queue. In order to track that it makes more sense to use a pointer instead of using a bitmap which must be search in order to locate the ring on an adapter index. As such I am changing the code to use pointers and an iterator to access all rings on a given q_vector. Signed-off-by:

This change cleans up the accounting needed at the start of xmit_frame so that we can avoid doing too much work to determine how many descriptors we will need. Signed-off-by:

This patch drops the use of eitr_low and eitr_high as values being stored in the adapter structure. Since the values have no external way to be changed they might as well just be hard coded values and save us the space on the adapter structure. Signed-off-by:

The IXGBE_FLAG_RX_CSUM_ENABLED flag is redundant since NETIF_F_RXCSUM is keeping the value we want to already have. As such we can drop the redundant flag and just make use of NETIF_F_RXCSUM. Signed-off-by:

There is a large amount of code present in this driver to support features that either do no exist or are not supported such ask packet split, DCA, or RSC. This patch strips out almost all of that code and in the case of conditionals based on unused flags I am flatting the code out to just the path that would have been selected. Signed-off-by:

Implement the RFC 5691 mitigation against Blind Reset attack using RST bit. Idea is to validate incoming RST sequence, to match RCV.NXT value, instead of previouly accepted window : (RCV.NXT <= SEG.SEQ < RCV.NXT+RCV.WND) If sequence is in window but not an exact match, send a "challenge ACK", so that the other part can resend an RST with the appropriate sequence. Add a new sysctl, tcp_challenge_ack_limit, to limit number of challenge ACK sent per second. Add a new SNMP counter to count number of challenge acks sent. (netstat -s | grep TCPChallengeACK) Signed-off-by:

Typically, the return value desired for the failure of a function with an integer return value is a negative integer. In these cases, the return value is sometimes a negative integer and sometimes 0, due to a subsequent initialization of the return variable within the loop. A simplified version of the semantic match that finds this problem is: (http://coccinelle.lip6.fr/) //<smpl> @r exists@ identifier ret; position p; constant C; expression e1,e3,e4; statement S; @@ ret = -C ... when != ret = e3 when any if@p (...) S ... when any if (\(ret != 0\|ret < 0\|ret > 0\) || ...) { ... return ...; } ... when != ret = e3 when any *if@p (...) { ... when != ret = e4 return ret; } //</smpl> Signed-off-by:

The driver currently skips setting this flag if the VPD contains the firmware version string. We fix this by separating the probing of NCSI from the reading of the NCSI version string. The APE_HAS_NCSI flag is needed to properly read sensor data. Signed-off-by:

netem does an early orphaning of skbs. Doing so breaks TCP Small Queue or any mechanism relying on socket sk_wmem_alloc feedback. Ideally, we should perform this orphaning after the rate module and before the delay module, to mimic what happens on a real link : skb orphaning is indeed normally done at TX completion, before the transit on the link. +-------+ +--------+ +---------------+ +-----------------+ + Qdisc +---> Device +--> TX completion +--> links / hops +-> + + + xmit + + skb orphaning + + propagation + +-------+ +--------+ +---------------+ +-----------------+ < rate limiting > < delay, drops, reorders > If netem is used without delay feature (drops, reorders, rate limiting), then we should avoid early skb orphaning, to keep pressure on sockets as long as packets are still in qdisc queue. Ideally, netem should be refactored to implement delay module as the last stage. Current algorithm merges the two phases (rate limiting + delay) so its not correct.

skb_fill_rx_data() pulls 64 byte of data in skb->data Its too much for TCP (with no options) on IPv4, as total size of headers is 14 + 40 = 54 This means tcp stack and splice() are suboptimal, since tcp payload is in part in tcp->data, and in part in skb frag. Signed-off-by:

The hash size is doubled when it needs to grow and compared against hash_max. The >= comparison will limit the hash table size to half of what is expected i.e. the default 512 hash_max will not allow the hash table to grow larger than 256. Also print the hash table limit instead of the desirable size when the limit is reached. Signed-off-by:

Userspace implementations of network routing protocols sometimes need to tell RA-originated IPv6 routes from other kernel routes to make proper routing decisions. This makes most sense for RA routes with nexthops, namely, default routes and Route Information routes. The intended mean of preserving RA route origin in a netlink message is through indicating RTPROT_RA as protocol code. Function rt6_fill_node() tried to do that for default routes, but its test condition was taken wrong. This change is modeled after the original mailing list posting by Jeff Haran. It fixes the test condition for default route case and sets the same behaviour for Route Information case (both types use nexthops). Handling of the 3rd RA route type, Prefix Information, is left unchanged, as it stands for interface connected routes (without nexthops). Signed-off-by:

Lenght field should be encoded using big endian byte order, such as intend in the specs. As it is currently written, the len field would not be decoded properly on an implementation using the correct byte ordering. Hence, it could lead to interroperability issues. Also, I rewrote the code so that iphc0 argument of lowpan_alloc_new_frame could be removed. Signed-off-by:
